  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • ffmpeg live transcoding faster alternative ?

    23 novembre 2018, par ppoeas

    Is there any opensource alternative to ffmpeg and VLC to live video transcoding from HTTP streaming to RTMP or other ?

    ffmpeg caused my CPU (AMD 4.0GHZ 8Core) is loaded 100% with only 8 SD streams.

    Thanks for help.

    PS.
    I think I don’t need to transcode my video, I can also stream with something like http video proxy. Source is in HTTP streaming format, also I am under Linux.

  • WMF EVR stops sending MEStreamSinkRequestSample event 7 seconds into the live stream

    18 décembre 2018, par asafrob

    I’m writing a WMF custom media source.
    This source gets h264 packets from an RTSP stream(using FFMPeg 4.1), and sends them to a decoder and renders them to screen with an EVR. It also sends them to an encoder, and a file writer

    For the first 7 seconds video looks good
    after 7 seconds FPS changes from 30 to 2 and the EVR shows an old image as an artifact (it is shown instead of the missing frames).
    The recorded video looks fine.

    running MFTrace I found that the renderer stops sending the MEStreamSinkRequestSample, so the source that have data to send (and raises MEMediaSample as before) does not send the sample.
    The samples only reach the decoder’s ProcessInput, and I can’t see the ProcessOutput calls.
    According to my logs there are no B frames (pts == dts) and both are monotonic with normal looking timestamps

    These are the log lines for the last frame that reached the EVR

  • Live Stream using .m3u8 and .ts files with iPhone as server

    26 février 2015, par Bhumit

    I am trying to accomplish a task to live stream from iPhone camera. I have done some research and found that i can use .m3u8 files for streaming live video with should contain .ts(Mpeg-2) files .

    Now the file which i have on my iPhone is .mp4 file and it does not work with .m3u8, so i figured out i will have to convert .mp4 to .ts for that , but i have not succeeded in doing so.

    I found that it is possible to convert video ffmpeg lib as mentioned in this article here. I have successfully imported ffmpeg library but not able figure out how can i use it to convert a video as i am using this for first time.

    One another thing apple documentation says

    There are a number of hardware and software encoders that can create
    MPEG-2 transport streams carrying MPEG-4 video and AAC audio in real
    time.

    What is being said here ? is there any other way i can use .mp4 files for live streaming without converting them from iOS ?

    Let me know if i am not clear, i can provide more information .Any suggestion is appreciated. I would like to know am i on a right path here ?

    EDIT

    I am adding more info to my question, so basically what i am asking is , we can convert .mp4 video to .ts using following command

    ffmpeg -i file.mp4 -acodec libfaac -vcodec libx264 -an -map 0 -f segment -segment_time 10 -segment_list test.m3u8 -segment_format mpegts -vbsf h264_mp4toannexb -flags -global_header stream%05d.ts

    How can i use ffmpeg library to do what this command does in iOS.
